Specication of Iietter's Patent.

Patented Sept. 17, 1918.

Application iled October 3, 1914. Serial No. 864,906.

To all whom zt may concern.'

Be it known that I, JOSEPH PERNA, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Tunnel and Trench Excavating Systems, of which the following is a specification.

y invention relates 'to new and useful improvements in tunnel and trench excavating systems, and has for its object to provide an exceedingly simple and effective device of this character, whereby the time, labor and'expense required in excavating tunnels and trenches may be greatly decreased.

A further object of the invention is to provide a new and useful improvementin carriers which are used in excavating work. A still further object of the invention is to provide a switch point for use with tracks as generally installed at the present time.

With these ends in view this Vinvention consists in the details of construction and elements hereinafter set forth and then specifically designated by the claim.V

In order that those skilled in theart to which this invention describe its construction in detail, referring by numeral to the accompanying drawing formingY a part of this spe'cication, in whichp Figure 1, is a transverse sectional view of a tunnel showing my system installed and illustrating the bucket ready to be withdrawn. A

F ig. 2, is a longitudinal sectional view thereof, showing the bucket slightly lowered.

Fig. 3, is a plan view of the track showing the switch point/for transferring the carriage fromy the main track to either of the l sidings.

Fig. 4, is a side elevation thereof. Fig. 5, is an enlarged elevation of the switch point;

Fig. 6, is a plan view thereof; and

Fig. 7, is a perspective view of a section of track, showing a modified form of the means for separating the traveling guides.

In carrying` out my invention vas here embodied 2 represents a tunnel having uprights 3'therein'andcross beams T4 and 5 secured thereto, Tothe cross beams 4' are'Y secured appertains mayvunderi stand how to make and use the same, I will the supports 6 arran ed in airs as plainly shown in Fig. 1. Eah of thIe sup orts comprises a horizontal body portion adapted to engage the top of the cross beams 4, having one end bent downward to form the depending finger 8 which engages one side of the cross beam to prevent the accidental displacement of the support. From the opposite end of the body portion 7 projects a downwardly extending arm 9 from the end of which is formed the hook 10 lying at right angles to the body 7 The hook of each pair of supports engages the upper flange of the track 11 preferably in the form of an I beam, thereby suspending the track from the cross beams 4.

12 denotes the hanger comprising side walls 13, each having secured thereto the shafts 14 on which are journaled the wheels 15, said wheels adapted to run upon the lower flange of the I beam track. In the side walls 13 of the hanger is also mounted an axle 16 on which is journaled the grooved wheel or pulley 17 over which operates the hoisting rope 18, one end of said hoisting rope having secured Vthereto the support connection 19 comprising a link 20 for fas.- tening the connection to the hoisting rope., a supporting link 21 and the ook engaging the link 23 carried by the bail 24 of the dumping bucket 25. The supporting link is of link 20, thereby forming shoulders .which when the support is drawn upward toward the hanger will engage the transverse rods or bolts 51 carried by the hanger to prevent the support connection from belng drawn into the vgrooved pulley, said rods hanger together and bracing the same. The side walls 13 of the hanger are provided with elongated openings 26, so that when the bucket is hoisted to bring the supporting greater width than the.

hook 22, said -or bolts also holding the side walls of the fr link 21 into alinement with the openings 26, l

a pin 27may be placedin said openings and through the link 21, thus relieving the hoisting rope 18 of the weight of the bucket and its contents andv permitting said hoisting rope to be used from the excavation.

I have here described the carrier as being drawn out from the excavation, whether in the form of a tunnel or trench, by meansof for drawing the carrier a hoisting rope and it is te be understood Vings, the ends of that either steam, electrical, hydraulic or handvpower may be used to operate the same, and if found desirable the hoisting rope may be entirely eliminated, j and the carrier manually pushed from the excavation.

'The side Walls 13Y of the.. hanger` yare further provided With holes 28 through which a pin 29 or its equivalent may be passed and then insertedin one of the holes 30 in the Web of the I beam trackto hold the carrier in any desired position While the bucket is being. filled, or a pin mayy b e placed inone of the .holes 30, Aand usedfas a stop to limi-t the inward tra-vel ofthe carrier.

They hoisting rope 18- is supported and guided by the traveling guides 31, each mounted upon Wheels 32 arranged to run upon thelovver flange of the Lbeam track, and each having journaled. therein another Wheel or .pulley 33' over which the hoisting rope18 runs and is prevented from sagging and! obstructing the Workmen;

Each'of the travelingguides are-fastened together and tothe hanger by chains 34, or their equivalent which properly space said traveling guidesas. they pass intol the excavation, and when the carrier isy being Withdrawn from the excavation it will engage saidl traveling guides successively, pushing themY out before it. *Y

Where the Work being done Will permit the suspendingv of the track at an anglethe carrier and the traveling'guides will run into the excavation by gravity, but Wherev it is necessary to suspend the track on an` ap; proximately horizontal line, I findthat it is necessary to draw the carrier into the eX- cavation, and to do so I provide a rope, cable, or its equivalent 35vvhich is attached to the hanger and runs over a sheave at the inner end. of the excavation so that Vby, drawing upon said rope the carrier Will be run tothe proper position.

In. Figs. 3 to 6 I have shown my improved means for transferring the carrier from one track tol another, in Which 11 represents the main track While 36 and 37 denote tvvosidthe sidings 36 and 3 7'being spaced from the. end of themain'y track 11' and between the adjacent ends is interposed-the switch point 38 of the same shape and'size as the track and sidings, these being here illustrated as made from I-beams.

One end of the switch point is arcuate or .convex in shape as at 39 to correspond With the concave end 40'of'the main track 11, and this end of the switchpointis supported by a rod 4lfvvhich passes through the hole'42in the upper ange'and projects intok the cut- -avvay portion or cavity 43 Vformed inthe Web, and on the inner end ofV saidV rod is mounted-.a nut 44, said .rodpivoting the switchA point inits, position adjacent the end .of .the maintrack 11.A The opposite end of thev switch point is supportedxby ame,-

tallic strip 45 which. passes through a slotv 46 in the yWebof4 the .switchlmpoint just below the upper flange, and said metallic strip 45 is .supported at its endsinvany suitable manner as by the uprights 47." Y

After the carrier-moved along the main track 11 Vand itis desired to run the same upon ,one of the sidings 36 and 37 the movable end ofthe switch point 38 is moved inthe desired.,.directionalong the metallic strip 45 to bring said switch point in alinement With the desired siding; at..rvhich time the .carrier Will proceed along' lieti-ack. in theordinary manner., passing p over the. switch 38 to the desiredY sid,- ing 36 or37;Y

In Fig.4 7 I .have shown a .slightlyimodij fied form of; the .means forspacing thedifferent traveling guides as they-.pass :into the excavation, inv which'fI 4pr-'ovideeachofgsaid traveling guides Withlprojecting arms 38, the length ofV .the arms of each; succeeding guide being longer'than the precedingeone, and these arms areiadapted; tot contact :With the inverted U: tshapedstops 49.ecarried by the track. and placedy at the. arms of said U haped'- stops being spaced from ytheftrack, theY onenearest the openingI orbeginning r`of the excavation having. its' arms spacedthe greatest'distance from, thecmain"v track i 11 l suitable'intervals,

is unnecessary vtochain the travelingguides to the carrier, yet-theyvvill'be stopped/at the proper points; to holdilthe rope :above the heads of the Workmen or out of theWayof their tools.. Y

Of course I donot Wish to .be limited to the exact details of :construction as hereshotvn,

as these may be varied Within thelimits of the appended claim-.Without departing from.thespiritxofmyinvention. 1
